JOHN COLLIS, OF DES MOINES, IOIVA.

PIPE-HANGER.

SPECIFICATION forming part of Letters Patent No. 411,518, dated September 24, 1889.

Application filed March 27, 1889. Serial No. 304,923. (No model.)

To all whom it may concern.-

Be it known that I, JOHN COLLIS, a citizen of the United States, residing at Des M oines, in the county of Polk and State of Iowa, have invented a new and useful Improvement in Pipe-Hangers, of which the following is a specification.

My invention relates to an improvement in pipe-hangers of the class commonly employed in buildings for suspending horizontal steam or other pipes under ceilings or the like; and my object is to provide a device of the above class of simple and improved construction, which shall be capable of ready adjustment in its operative position and be easily separable to facilitate the suspension or removal of the pipe it is designed to sustain.

My invention consists in the general construction of my improved device; and it further consists in details of construction and combinations of parts, hereinafter set forth and claimed. 1

In the drawings, Figure 1 is ta view in elevation, partly sectional, of a pipe-hanger of my improved construction in operative position, supporting a pipe which is indicated by dotted lines; and Figs. 2 and 3, a perspective and broken perspective view, respectively, showing details.

A A are the side pieces of a stirrup, which may be curved throughout part of their extent (though I do not limit my invention to this particular form) and flanged toward 0pposite ends, as shown, to afford flat opposing extension t t ands s. The upper flanges t are provided with openings 15' and the lower flanges s withopenings to receive a nu t-bolt r. A roller q fits loosely over the bolt r be tween the opposing flanges s s.

B is a yoke comprising a body portion 13, having longitudinally an opening 19', and lugs 0, projecting from opposite sides of the body. portion, provided with shoulders 0, which extend upward and produce sockets 0 between them and the body portion of the yoke.

In adjusting my improved hanger in operative position the yoke 13 is secured to the ceiling or other overhead support by means of a lag-screw y, or other suitable securing means, which extends through the opening 19 or beyond the body portion of the yoke. The stirrup is adjusted around the pipe and the openings 15 of the side pieces A passed over the lugs 0 of the yoke, whereby the upper sides of the openings 25 are caused to rest in the sockets 0 as shown in Fig. 1. Thehangers may be raised or lowered to adjust them to the proper level or pitch by turning the screw 11 to the right or left. The rollers q operate to practically do away with the strain upon the hangers which the longitudinal shifting back and forth of the line of pipe in coupling and uncoupling, or the expansion and contraction thereof due to changes in temperature, would otherwise occasion, which strain, more especially in the case of the heavier pipes, would tend to injure the hangers, and while for the above reason the rollers are very desirable they are not indispensable.

My improved hanger constructed as described affords a secure suspension medium for the pipe, and may be quickly placed in operative position, adjusted, and removed, and, as it is made up of several small and separable parts, should one part become broken it may be replaced at but slight expense.

What I claim as new, and desire to secure by Letters Patent, is

A pipe-hanger comprising, in combination, a stirrup formed with side pieces A, secured together toward their lower ends by a bolt 4, a roller (1 on the bolt between the side pieces, openings 6' in the side pieces toward their upper ends, a yoke B, having lateral projections 0 to enter the said openings, sockets 0 in the projections 0, to receive the upper sides of the said openings, and means for suspending the yoke to a support, substantially as described.
